OpenRD .. finally


yay. finally I managed to mangle my OpenRD Client board .. sigh

I had troubles, that the marge of my dev board was never stating the correct
manufacturer ID for the NAND, which made flashing newer Uboot bootloader im-
possible.

This was the error popping up whatever I tried with Uboot/OpenOCD ...

unknown NAND device found, manufacturer id: 0x00 device id: 0x00
probing failed for NAND flash device

It drove me nuts until found a solution [1]. Yay!

Now with a newer Uboot (v3.4.19) I was suddenly able to install Debian on the
SD/MMC. For that I followed the great Howto under [2].

Heh, nice. So it finally boots Debian .. and having the D-I via serial console
in my screen (hint: screen tops minicom a million times: screen /dev/ttyUSB0 115200)
just feels very nice :)

But then I got hot and wanted moar .. MUAHAHA !! .. I finally have put the Debian
install from the SD/MMC onto the internal flash, but not before converting that
flash to UBIFS, following this guide [3] ff.

Heh, so now I have an OpenRD Client, booting Debian on choice from SD/MMC or the
internal flash with either kernel 2.6.32-5-kirkwood from Debian or the Sheevakernel
from [4] with 2.6.35.3 ..

I love it!

Further down I have a list with more good-to-read-in-case-links.

hackers, homeopathy and arrogance

Ever wondered why it currently seems so fashionable for hackers to bash on homeopathy ?

well, we got ... numberz ! and to be less boring, put them into some pictures that give a relation.

First of all, lets see for what kinds of people homeopathy actually works and for whom not:

average effectiveness

works for.png

strange, heh ?

well, theres moar: as demonstrated, it is easy to understand that people only choose the data that is sufficient to prove their claims. in the current homeopathy bashing, most arguments go on about the theoretical possiblility of any effect based on the amount of thinning of a given substance.

as paracelsus stated that success alone will tell, this gives quite a different picture:

use only datasets that fit into your mindset

schusters leisten.png

hm... so, really, if someone believes something is completely harmless, then why hit on it ? the winner is quite clear:

who has an advantage

2-sponsored by pharma industry.png

100%

a clear winner at 100 per cent, not mentioning the small fry companies and users that are hurt by it.

To deviate a bit, an analysis of the hacker mindset in relation to alternative medicine seems in order.

As everyone is a computer expert these days, it should be mentioned that most computer people can maintain an overview over complex matter.
It should however also be mentioned that it mostly only applies to their own field of interest and proficiency and horribly fails at other systems.

hackers

3-system theory.png

Does that mean if they cannot maintain a feeling for a complex system outside of their domain it will equally be impossible to still take them seriously ?

It is about time for some lowkicks.

We shall take a look at their self image and how it deviates from reality.

Taking into account that they have access to a lot of information on the interwebs, this might suggest an onmisciencent belief system coupled with some more illusions:

omniscient beliefs

4-hackers believe they know all.png

reality shows a different picture, one of delusion.

This leads us to the difference between life and its skewed image in the mirror of the web:

delusions

5-hackers believe they know a lot.png

For people who are strictly to adhere to the dogma of duality expressed in ones and zeroes, anything fuzzy is an unlikely encounter:

a straight mindset

6-straight vs hip.png

But what the heck anyway, would you rather get an operation by a computer-illiterate surgeon or a hacker believing he/she knows about medicine ? How often have hackers helped you medically ?

What if conventional medicine fails ? If alternative medicine were totally non-effective, how could it hurt trying an alternative ?

fact is that there is a significant amount of so-called hopeless cases that were solved by "ineffective and unscientific" means.

doh.

7-who or what helps.png

To be able to spot a hunch of an explanation, we need to leave the rational battlefield and enter martial arts. This view allows us to pinpoint a fundamental difference between hackers and medics from any field.

The Difference

8-chi levels.png

This clearly gives an indication that a certain energy level needed to administer and receive alternative medical treatment is lacking at our aforementioned subjects.

Life is not a game where Experience Points can be gained by sitting in front of a screen and clicking at the things that pass by.

On the contrary, using computers for several times a day leads to a deprivation in energy that cannot adequately be quenched by pizza:

computers suck

To increase the amount of MediPacks (ie. Health), it makes sense to turn the box off once in a while and stop bitching about stuff one does not have a clue about.

lucid and ssh-agent

for ages, i had my ssh-agent settings in my .bashrc. with lucid this setup stopped working.

i had to - tell gconftool to not intermingle:

gconftool-2 --set -t bool /apps/gnome-keyring/daemon-components/ssh false

which did not do much. as an ugly hack, i additionally just disabled my own ssh-agent handling if it runs on lucid:
    # ssh-agent stuff
    # broken with ubuntu lucid
    distro=lsb_release -c | sed -e 's/Codename://g' | grep lucid
    if [ ! -z "$distro" ] ; then
                #echo "$distro detected, aborting ssh-agent logic"
                echo $- | grep i > /dev/null
                noninteractive=$?
                if [ "$noninteractive" == 0 ] ; then
                    ssh-add -l >& /dev/null
                    if test $? = 2; then
                         if test -f ~/.agent; then
                                 . ~/.agent
                         fi
                         ssh-add -l >& /dev/null
                         if test $? = 2; then
                                 ssh-agent > ~/.agent
                                 . ~/.agent > /dev/null
                         fi
                    fi
                fi

Panzerpappe: Wie viel Geld spart der Staat eigentlich, wenn die Hartz-IV-Empfänger den WInter nicht überleben @kristinakoehler?

zeitweise: Würde mal sagen, @kristinakoehler wollte nur mal rausfinden, wie wie sich soziale Ächtung am eigenen Leib anfühlt. Ich nenne das Bürgernähe.

??: Eine Ministerin erhält 12.860€/Monat vom Staat + Nebenverdienste. Ist das gerecht gegenüber denen, die arbeiten?
